The Rehabilitation and Research Centre for Torture Victims in Copenhagen has initiated work towards creating the Thesaurus of Torture Terminology (T3); a thesaurus of terminology related to torture, prevention of torture, and rehabilitation of torture victims. The work is coordinated by the RCT Documentation Centre, with the support and cooperation of an International Working Group. The T3 project aims to create a structured vocabulary sufficiently extensive and detailed to facilitate indexing and retrieval of documents on torture, at a level suited to specialists in the fields of torture prevention and rehabilitation of victims. The thesaurus will be created in English; it is hoped that translations/adaptations into other languages can be undertaken subsequently, possibly in cooperation with interested organisations in the human rights field.
